Investigation & Root Cause Analysis Own end-to-end investigation of ad-hoc technical issues raised by product, operations, or engineering teams.
Diagnose data integrity problems by tracing issues across event streams, APIs, and database layers.
Analyse Kafka event histories to reconstruct system state and identify where data diverged from expected behaviour.
Produce clear root cause analysis (RCA) documentation that explains what happened, why, and how to prevent recurrence.
Data Analysis & Resolution Write complex SQL queries against production and staging databases to investigate data anomalies, gaps, and inconsistencies.
Validate proposed fixes in lower environments before escalating to production resolution recommendations.
Use REST APIs to probe system state, trigger reprocessing workflows, and verify expected outputs.
Collaborate closely with software engineers to understand system internals and escalate findings with sufficient context for developers to act.
Produce concise, structured investigation reports suitable for both technical and non-technical audiences.
Maintain a knowledge base of known issues, recurring patterns, and resolution playbooks.

Solid background in software development
you should be able to think like a developer even if you are no longer writing production code.
Demonstrable experience investigating complex systems issues in a professional environment.
Strong analytical mindset with the ability to form and test hypotheses methodically.

Comfortable working with unfamiliar data models and reverse-engineering schemas without full documentation.
Experience working with relational databases (e.g. PostgreSQL, MySQL or similar) in a professional context.
Ability to reason about data consistency, referential integrity and the impact of partial failures on stored state.
Strong understanding of REST API design principles, including HTTP methods, status codes, request/response structures and authentication patterns.
Proficient with Postman or equivalent tools for constructing, executing and inspecting API requests.
Ability to read and understand Scala code (Functional and OO), particularly around data transformation logic, event handlers and domain models.
Highly curious, with a genuine interest in solving complex, ambiguous technical problems.
Strong collaboration and communication skills, with the ability to work effectively alongside software engineers, data teams and product stakeholders while adapting technical findings for different audiences.
